SOLE-PRESSING MACHINE.

Specification of Letters Patent.

Patented Sept. 26,1911.

To all whom it may concern:

Be it known that I, EDWIN N. PREBLE, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Sole-PressingMachines; and I do hereby declare the 01 lowing to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The present invention relates to sole press ing machines of that classwhich comprise cooperating sole pressing forms adapted to operate upon asole before it is incorporated in a shoe.

Machines of the class above referred to have been provided with sologaging and ipping devices associated with one of the orms to enable thesole to be placed in the desired position with relation-to the forms andto prevent the sole from being displaced during the action of the for: sthereon.

The ob'ects of the present invention are to 'provi e sole moldingmachines -of.the class above referred to with so e aging and grippingdevices which are si 1. 'ie'r in construction and more durable thanthose which have heretofore been devised. and to arrange and actuate thesole aging and ripping devices in an improve? manner so t at they aremore efiicient in operation and so that the forms can'be more readilyremoved from and inserted in the machine.

.W'ith the above objects in view, the present invention consists in thedevices, combinations and arrangement of parts hereinafter described andclaimed, the advantages of which will be obvious to those skilled in 40the art from the following descri tion.

a In the drawings accompanying t is application the present invention isillustrated as applied to a sole moldin machine of that type in whichthe lower so e molding form,

inaddition to a reciprocating movementtoward'and from the upper formto'produecressure and clearance, also has a horizbntai transversemovement into and out of lalinement'with the upper form, from and towarda position of resentation, that is, a position onvenient y accemible bythe operator for the removal and insertion of soles. It is to beunderstood, however, that certain features of the invention are notlimited to use in this type of sole molding machine, nor is theinvention, except as defined in the claims,'limited to any particularconstruction or arrangement of parts.

The several features of the present invention will be clearly understoodfrom an inspection of the accompanying drawings in which-- Figure 1 is alongitudinal vertical sectional view of a portion of a well-known typeof sole molding machine with sole gaging and gripping devices embodyingthe several features of the present invention in their preferred formapplied thereto. Fig. 2 is a detail plan view, partly broken away, ofone of the lower form carrying slides with a lower mold thereon togetherwith sole gaging and gripping devices associated therewith. Fig. 3 is alongitudinal sectional view taken on the line 3-3, of Fig. 2.

Fig. 4 is a cross sectional view takenoin" the line 44, of Fig. 3. Fig.5 is a detail view in side elevation of the spring rcssed bell cranklever and its supporting )racket by which the movable jaw of thegripping device is actuated. Fig. 6 is a detail tional view taken on theline 6--6, of Fig. 3, illustrating particularly the manner in which theheel gage is mounted and the con nection between the heel ga e and itsadjusting mechanism. Fig. 7 1s a detail seetional view of a port on ofthe mechanism for actuating the heel go o and indicating its ositior.aken on the ine 7-7, of Fig. 3. *ig. 8 is an underneath plan view of aiortion of the mechanism illustrated in Fig. Fig.9 is a detail plan viewof a modified form of heel gage adapted for usewi'th either completelyrounded soles or with what. are known in the art as block soles, theheel ends of which present a straight instead of a rounded edge. Fig. 10"is a detail plan viewsimilar to Fig. 9 but showing the arms of the heelgage in position to coiiperale with a blocksole and Fig. 11 is a. detailview in side elevation of the parts illustrated in Fig. 9. x v

The machine, a portion of which is illustrated in Fig. 1, is a doublemachine, being provided with two sets of cotipt-arating sole pressingforms, the upper forms being stationary and the lower forms beingreciprorated simultaneously in opposite directions cured in tin usualmanner upon a carrier 2 which is supoorted from the stationary crosshead 3, so to be adjustable vertically, by means of an adjusting wedge4. The lower form is indicated at 5 and is removably mounted upon aslide 6 which reciprocates in a horizontal guideway formed on a verticalreciprocating cross head I. lleaziproeating movements are imparted tothecross head 7 from a crank shaft 8 by means of a link 9 and togglelevers 10. Reciprocating movements are imparted to the slide 6transversely to the reciprocating movements of the cross head 7 by meansof a bell crank 11 which is mounted upon the cross head 7 and has onearm connected to the slide 6 by means of a link 12, the other arm of thebell crank being connected by a link 13 to an arm 14 integral with a.rock shaft or sleeve 15 journaled on the frame of the machine. An arm 16extends rearwardly from the rock shaft 15 and is connected by a coiledspring 17 to the stationary cross head 3. During the rising and fallingmovements of the cross head 7 the bell crank 11 is rocked and impartsinward and outward movements to the slide 6. The inward movement of theslide 6 is limited by a cross piece 18 at the rear end of the guidewayof thc-slide. The form carrying slide on the opposite side of themachine, corresponding to the slide (5, is actuated by a similar bellcranlv which is connected to another arm rigid with the rock shaft. 15,the arrangement of the bell cranks and slides being such, as will beapparent from an inspection of Fig.1, that.

the reciprocating movements of'the slides take place during'the lowerhalf of the reciprocations of the cross head 7 and its correspondingcross head in each direction.

The parts so far described and the other parts not hereinafterspecifically referred to are the same in construction and mode ofoperation as corresponding arts of a sole molding m h ne which hasieretofore been devised an in and of themselves formno part of thepresent invention. V i The solegaging' and gripping devices,

illustrated in the drawings as embodying the several features of thepresent invention, comprise a heel gage to determine the position of thesole with relation to the lower form, and a sole ripping device whichengages opposite surfaces of the solo atthe heel end and holdsthe solein position during the operation of the forms thereon. It is oftendesirable, and when certain kinds of soles are to be operated upon it isnecessary, to use a sole molding machine without heel gaging andgripping devices. The heel gage and. gripping device illustrated in thedrawings are accordingly removably mounted in the machine, and to enablethe gage and gripping devices to be removed without disturbing therelative position of the gage, which is adjustable for soles ofdifferent sizes. and the gripping devices, the gage and gripping devicesare mounted upon a single carrier. This carrier is indicated in thedrawings at. 19, and to permit the lower form to be readily removed anda form of a ditl'erent size or style substituted therefor withoutdisturbing the heel gage and gripping device, the carrier 19 is securedto the form carrying slide 6 independentl of the lower form. The carrier19 exten s longitudinally ot the slide 6 and its rear end is received ina slot formed in a plate 20 bolt;- .(l to the rear end of he slide. Thecarrier is removably held in position on the slide by means of a pin 21,engaging a recess in the front end of the carrier, and by means of ahand operated clamping lever 22 mounted upon the plate 20 and provided.with an inclined cam surface 23 engaging a correspondingly inclinedsurface on the rear end of the. carrier. A movement of the lever 22 inone direction securely clamps the carrier 19 in position, while amovement of the lever in the opposite direction releases the carrier andpermits it to be moved to the rear and raised from the form carryingslide.

it is desirable in sole molding machines to use a complete lower form inpreference to a lower form having the heel portion cut away or omitted,since the heel portion of a complete form presents a support for theheel portion of the sole while being placed in position and also theheel portion of the form atl'ords a means by which the form can he moresecurely held upon the form carrying slide. The heel gaging and grippingdevices illustrated in the drawings are accordingly constructed andarranged to cooperate with a complete lower form and to enable the gageand gripping devices to be placed in the desired position with relationto the. form, the form is provided at its heel end with a longitudinalslot. The forward end of the carrier .19 projects into this slot andsnugly fits the slot so that the forward Will of the carrier serves as ameans for se- Me since.

The carrier for the heel gage and gripping v device thus performs thefunction of one of the usual form retaining pins projecting from theform carrying slide. The other retaining pin is indicated at 24.

The sole gripping device illustrated in the drawings comprises astationa.ryjaw,25,consisting of the head of a pin mounted in the forwardend of the carrier 19, and a movable jaw 26 pivotally mounted betweenears pro jecting upwardly from the rear end of the carrier. The movablejaw 26 is opened and closed during .the reciprt eating movements of theform carrying slide so that the sole is gripped before the lower formcomes into alinement with the upper form and is released by the time thelower form reaches its position of presentation. To actuate the jaw 26during the movements of the form carrying slide, an arm carryin r a roll27' is provided, which roll is arrang to rest upon the upper surface ofthe jaw 26 and to travel along the jaw during the reciprocatingmovements of the slide. The arm carrying the roll 27 projeats laterallyfrom the horizontal arm of a bell crank 28 pivotally mounted on abracket 2) secured to the cross hea 1 7. A rod 30 is mounted at one endin a flange of the bracket 29 and at its other end extends through ahole in the lower end of the vertical arm of the hell crank.

A coiled spring 31 surrounds the rod 30 and is interposed between thevertical arm of the bell crank and a flange on the bracket 29 so thatthespring acts to hold the roll 27 yieldingly in engagement with thegripping jaw 26. During the backward movement of the form carrying slidethe roll 27 holds the gripping jaw yiel lingly pressed against the sole.During the outward movement of the k form carrying slide the roll 27travels along the gripping jaw 26 and passes from one T sideof its pivotto the other so that the pressure of the spring 31. is no longeroperative to keep the jaw closed. To open the jaw a stop in the form ofa block 32 is mounted upon the rear end of the gripping jawin positionto be engaged by the roll 27 as the form carrying slide reaches thelimitof its outward movement. To regulate the distance to which the jaw israised in being "opened the block 32 is adjustably secured to the jaw. Ahand lever 33 projecting rearwardly from the hub of the bell crank 285'5 serves as a convenient means for raising the l h v n roll 24 fromengagement with the aw 26 when the carrier 1915 to be removed from themachine.

i The heel gage illustrated in the drawings, 10 consists of two arms 34angular ly disposed with relation to each other, as best shown in qlg'kQ, and projecting from a block 35. The block 35is-carr1ed upon ablock 36 which is unmounted to slide on a rod 37 forming a part of thecarrier 19 so as to be capable of adjustment to adjustthe heel gage forsoles of difierent sizes. To enable the heel gage to be adjusted vertcally to bring it into the desired position with relation to forms ofdifferent thickness, the block 35 is mounted upon a horizontal pivot 38on the block 36 so as to be capable of swinging vertically. A springpressed locking pin 39, mounted in the block 36 and arranged to engage aseries of teeth 40 on a downward projection from the block 35. locks theblock and heel gage in adjusted position.

In the machine illustrated in the drawings the sole molding forms areplaced. in the ma; chine with their toe ends toward the front. The heelgage is thus remote from the operator and is not conveniently accessiblefor adjustment. To enable the ,heel gage to be adjusted readily by theoperator without loss of time, mechanism is provided connected to theheel age and extending to a point at the front 0 the lower form. Thismech anism includes a longitudinally movable rod or bar 41 which extendslongitudinally beneath the form carrying slide 6 and projects upwardlythrough a slot at the rear of the slide into position to engage aprojection from the block 36 upon which the heel gage is mounted as'isclearly shown in Fig. 3. The projection from the block 36 which isengaged by the rod 41 is indicated at 42 and is best shown in Fig. 6.This projection extends laterally from the block 36 and then downwardlyand is provided at its lower end with a pin which enters a hole in therod 4-1 so that the projection is readily disengaged from the rod whenthe carrier 19 is removed from the machine and the removal of thecarrier ispermitted without disttu'bing the gage adjusting mechanism.The mechanism for adjusting the heel gage also includes a shaft 43mounted in the forward end of the form carrying slidehin a verticalposition at right angles to the rod 41. This shaft is provided with apinion 44 which meshes with a series of teeth 4:53 on the foiwv'ard endof the rod 4-1, the construction being such that a mechanism againstmovement. These means as illustrated in the drawings and best shown inFigs. 7 and 8, consist of a locking arm 46 projecting laterally from thelower end of the shaft 43 and a series of locking teeth 47, arranged tohe engaged by the arm, formed on a plate rigidly secured to a stationaryblock 48 on the under side of the slide 6. The shaft 43 is mounted so asto be capable of moving longitudinally and is pressed upwardly in adire'ction'trrcause the arm 16 t0 enga e the teeth-17 by means of aspring 49 coi e around the shaft and seated between the bottom of arecess in the hlock 48 and the lower surface of the knob 50 securechtothe upper en of the shaft 43 affords a convenient means for moving theshaft 43 to disengage the arm 46 from the teeth 47 and for rotating theshaft to adjust the heel gage.

In addition to the sole gripping and gaging devices hereinbeforedescribed, the machine illustrated in the drawings is provided with animproved means for indicating the size of sole for'which the heel gageis ad justed. This means is extremely simple and compact in constructionand efficient in operation and comprises a pointer 51 formed on the knob50 and an annular scale plate 5! surrounding; the knob and provided witha series of numerals indicating the various sizes of shoe soles. Thisscale plate is mounted on the form carrying slide 6 concentric with theshaft 43 as best shown in is capable of adjustment to bring the numeralsinto the required position with Fig. 7, and relation to the knob 50 toindicate the sizes of soles of different kinds. The plate is held inadjusted position on the form carrying slide by means of a locking pin53 screwing into the slide and provide with a flange extending into acircumferential groove 54 formed in the edge of the plate.

The soles which are operated upon by a sole molding machine are eithercompletely rounded so that the edge of the heel end of the sole iscurved, or are what are known in the art as'block soles, the heel endsof which present a straight edge at right angles to the longitudinalaxis of the sole. in Figs. 9, l0, and 11 is illustrated an improved formof heel gage adapted for use with either of these classes of soles. Thisheel gage is similar in construction to the heel gage. hereinheforcdescribed with the exception that. the arms forming the heel mounted sothat they can be swung baclt into line with each other. In Figs. 9, l0,and 1.1. the two arms of the heel gage are in dieatcd at 55 and aremounted upon separate vertical pivots 56 on the gagecurryingbloek. Thearms 55 are capable of being swung from the angular position illustratedin Fig. A to a position in which they are in line with each other, asillustrated in Fig. 10. To hold the arms in either positionspringpressed locking pins 57 are mounted in the gage carrying blockengage notches 58 formed in the hubs ofthe arms. It will he noted thatthe pivots of the arms 5:") are separated a considerable distance. Byreason of this arrangement of the arms they are adapted to engage anddetermine correctly the position of a t-Lf lltl of a given size, whetherthe sole is a rounded sole or a block sole, .uithout the necessity ofany adjustment of the gage carrying block.
